Interpolation can be turned on and off for each channel.
Delay can be set for each channel.
100 ns to 10 ms
100 ns to 100 µs, in steps of 100 ns
101 µs to 1 ms, in steps of 1 µs
1.01 ms to 10 ms, in steps of 10 µs
Max. math rate: 10 MS/s or 1 MS/s for polynomials
Basic arithmetic:
Addition, subtraction, multiplication, and division of two channels (no coefficients)
Differentiation:
Differentiation using a fifth order Lagrange interpolation formula
Integration:
Integration reset condition: When waveform acquisition starts, when a channel is
turned on or off
Selectable reset conditions:
Over limit (±10 div)
Zero crossing to positive: When the source signal is moving in the positive
Zero crossing to negative: When the source signal is moving in the negative
Basic arithmetic with coefficients:
Expressions: +, –, ×, /
Coefficients: A, B, and C can be defined.
Addition: (A × S1) + (B × S2) + C
Subtraction: (A × S1) – (B × S2) + C
Multiplication: (A × S1) × (B × S2) + C
Division: (A × S1)/(B × S2) + C
Range of coefficients A, B, and C: –9.9999E+30 to +9.9999E+30
